Simple Cable Tidy [Horizontal Mount]

I've had a thin plastic cable tidy on my shelf for some time but it is now deformed with the weight of the cables I hung on it. I decided to design a simple replacement. It has 5mm, 4mm, and 3mm gaps to suit different cable ends and is simply secured with three screws from above. It is intended for mounting on an edge, I used the end of a shelf. It is also the first project I have designed in Fusion 360.
